Abstract

The invention discloses a novel high-efficiency PPR (pentatricopeptide repeat) pipe cold-resistant toughening color master batch. The color master batch comprises the following components in parts by weight: 5-25 parts of polypropylene, 5-10 parts of pigment, 35-65 parts of cold-resistant modifying agent and 1-15 parts of reinforced modifying agent, wherein the cold-resistant modifying agent is one substance or a mixture of more of styrene-butadiene-styrene ternary segmented copolymer, ethylene-vinyl acetate copolymer and ethylene-octylene copolymer, and the reinforced modifying agent is one substance or a mixture of more of nano calcium carbonate, nano silicon and the nano barium sulfate. According to the color master batch, the formula components of the color master batch can be optimized and improved, so that the novel high-efficiency PPR pipe cold-resistant toughening color master batch can be prepared. The color master batch provided by the invention not only can play a role in coloring, but also can obviously improve the flexibility and the shock strength of the PPR pipe under the condition of low temperature, so that the cold resistance of the pipe can be improved, and the service life of the pipe can be prolonged.

Description

technical field [0001] The invention relates to the field of polymer materials, in particular to a novel high-efficiency PPR pipe material cold-resistant and toughening color masterbatch. Background technique [0002] PPR is a new type of polymer material for plastic pipes developed and applied in Europe in the early 1990s. The gas phase copolymerization process is used to randomly and uniformly polymerize about 5% of PE in the molecular chain of PP, which has good processability. PPR pipes can be used as cold water pipes and hot water pipes, and the requirements for heat resistance and cold resistance in their use environment are relatively high. The current common color masterbatch only plays a coloring role, and its dispersion effect in pipe products is poor, and it cannot improve its functional requirements such as heat resistance and cold resistance. Contents of the invention [0003] In view of this, the present invention provides a new type of high-efficiency cold...
